SAMUEL I. MARTIN, OF DE GRAFF, MINNESOTA.

SWEEP-RAKE.

Specification of Letters Patent.

Application filed May 23, 1908.

Patented July 13, 1909.

Serial No. 434,686.

To all whom it may concern:

Be it known that l, SAMUEL l). MARTIN, a citizen of the United States, residingl at De Grail', in the county of Swift and State of Minnesota, have invented certain new and useful improvements in Sweep Rakes, of which the following is a speci'ficatien,1eference being had to the accompanying drawings.

My invention relates to improvements in sweep rakes, and its object is te improve and simplify the construction of devices of this character and thereby render the same less expensive and more durable and eflicient.

lilith the above and other objects in view the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed, and illustrated inthe accompanying drawings, in which- Figure 1 is a plan view7 with parts breken away, of my improved sweep rake; Fig, 2 is a side elevation; Figs. 3, 4 and 5 are detail sectional views taken on the planes indicated by the lines SMO, 4 4 and 5-5 in Fig. 1; Fig. 6 is a detail view of the seat support; and Fig. 7 is a detail perspective of the rearcnd of one of the end members of the body frame.

My improved rake comprises a body frame consisting of two similar' end blocks 1 which taper from front to rear and are connected at their front by upper and lower longitudinal bars 2, 3 and at their rear by a longitudinal bar 4. The lower front and rear bars 3, 4 are connected at intervals by cross bars 5, said bars 2, 3, 4, 5 having their ends mortised into eachother and the end blocks or heads 1 and secured by bolts or similar fastenings 6.

7 denotes the teeth of the rake. These teeth are arranged parallel to each other and beneath the cross bars 5 and the front and rear bars 3, 4 to which they are detachably This connection is effected by forming in the bottom edge of the lower or bottom bars 3, 4 of the frame transverse grooves or seats 8 te receive the rear portions of the teeth, the eXtreme rear ends of the latter being recessed or mortised, as at Q, te engage the recesses S in the rear bar 4 and to provide shoulders 10 which will prevent the teeth from shifting rearwardly. The teeth are secured in the recesses S of the bottom bars by U-shaped bolts or clips 1.1. which are passed over and arranged in seats 12 in the tops of the cross bars 5 and have their depending ends formed with eyes 13 disposed on oppositeI sides of the teeth and ad aptcd to register with transverse openings in the latter so as to receive removable bolts 14. lt will be seen that by constructing the frame and the teeth as illustrated and attaching the latter as inst described, said teeth may be readily disconnected from the frame to permit it to be stored away when not needed and that should the teeth break they may readily replaced by new ones.

15 denotes caster wheels, two of which are preferablyprovided for supporting the frame. T he hangers 1G of the wheels are swiif'eled to the lower ends of standards 17 which are ad justable both vertically and lwrizontally in supporting blocks or members 18. The blocks v1S extend crosswise of the frame 1 and have at their ends projecting portions or arms 19 which are bolted as at 20 to the bars 9, 3, 4. ln ythe blocks 18 are formed longitudinal series of vertical openings 21 in any of which the standards 7 may be inserted and adjusted vertically, preferably, by inserting removable pins or bolts 22 through transverse openings 23 in the blocks 1S and openings 24 arranged in said standards. A plurality of the openings 24 are arranged in each standard 17 so that any one of them maybe brought into register with the openings 23 in the block v1S to receive the adjusting pin 22.

Dctachably pivoted by a bolt :'25 upon the outer side o'f each of the ond blocks or heads l is a draft tongue or pole lo and projecting outwardly from each sido or end ofthe 'frame is an ovoner or draft bar 27. rl"he latter ha' adjustably mounted upon its outer end a whifflctree 2S and its inner end is detachably connected to the 'frame by two bolts 2E), 3l) the former of which is passed through the rear bar 4 and the latter' of which Vpasses through two rearwardly projecting lugs 32 projecting vfrom one of the end blocks or heads 1 and adapted to receive the evener bar 27 between them.

33 denotes a drivers sea adjustably secured upon a seat standard 34 which is loosely connected to the frame by a bolt 35 and is resiliently supported in an inclined position by a curved spring 36. The ends of the latter are secured at 37 to the frame and its central portion supports 'the standard S4 and is provided with foot rests 3S.

39 denotes a bar for spacing the outer portions of the teeth 7 apart and reinforcing them. This bar is preferably removably arranged upon the teeth by forming in its top recesses 40 to receive said teeth and by providing upon it above said recesses U-shaped straps 4l which project over the teeth. To retain the spacing and supporting bar 29 uponthe teeth I preferably provide in oertain of the straps 4l removable pins 42 which enter openings or sockets in certain of the teeth. Said pins 42 may be connected by straps or chains 43 to the bar 39 to prevent them from being lost.

Having thus described my invention what I claim is: f

1. In a device of the character described, the combination of a body frame having end members connected by longitudinal bars and cross bars connecting said longitudinal bars, teeth engaged with said longitudinal bars and having shoulders to prevent them shifting rearwardly, clips passed over the cross bars and engaged with the teeth and transverse fastenings passed through the clips and the teeth.

2. In a device of the character described, the combination of a body, rake teeth projecting forwardly therefrom, a spacing and strengthening bar having its upper edge recessed to receive the teeth, straps extending over the recesses of said bar to receive the teeth and pins passed through the' straps and into the teeth to secure said bar thereto.

3. In a device of the character described, the combination of a body, rake teeth projecting forwardly therefrom, a spacing and strengthening bar extending across and engaged with the forward ends of said teeth and means for detachably securing said bar to said teeth.

4. In a device of the character described, the combination of a body having end members provided at their rear ends with spaced lugs, longitudinal bars connecting said end members, teeth carried by said longitudinal bars, draft tongues or poles projecting forwardly from the end members, and draft bars or eveners projecting outwardly from the body .and having their inner ends secured to the longitudinal bars. and their intermediateiportions secured betweenthe spaced lugs on the end members.

5. In a device ofthe character described,

the combination "of a body frame having upright end members connected by longitudinal bars and cross bars connecting saidl longitudinal bars, rake teeth engaged with to preventfthem from shifting rearwardly,

clips detachably connecting the teeth to said cross bars, a draft tongue detachably connected to each of the end members and projecting forwardly therefrom, a draft bar or evener detachably connected to the end members and longitudinal bar of the body and projecting outwardly therefrom, and detachable caster wheels adjustable yboth vertically and forwardly and rearwardly'from the body, substantially as described. y

In testimony whereof I hereunto affix my signature in the presence of ,two witnesses.
